The most common numeral system used by måcku. It works like our Arabic (originally Indian) numerals but has eight as its base. Consequently, they stand for 1, 2, 3, 4, 5, 6, 7 and 0.The word ”vaenyjaa” [vænyjɔ] refers to a language related to Obokytan. The maacku which invented this numbering system spoke this language. This is why it is named so.
